Admob banner is not refreshing because of Show and Hide.

Hello,

My banner ads (from admob) are only shown in the GameScene, not in the others (IntroMenu, Shop). However, the banner does not refresh itself (even after playing something like 30 minutes) even with an automatic refresh time set on the admob banner configuration (60 seconds). I tested and if I dont make the "Show()" and "Hide()" calls the banner refreshes itself.

Anyone has any idea why this is happening or has spotted any good practice i'm skipping?

The calls I use:

Banner Instantiation and Loading

• BannerView myBannerView = new BannerView(...);

• myBannerView.LoadAd(...);

When starting the game

• myBannerView.Show();

When the player dies and goes back to the menu

• myBannerView.Hide();

ps.: I'm using GoogleMobileAds_3.1.2 plugin.
